BOOKBINDERS STRIP-APPLYING MACHINE.

Specification of Letters Patent.

Patented May 5, 1908.

Applicationled June 27, 1906. Serial No. 323,625.

T o all whom it may concern:

Be it known that I, CHRISTOPHER JOHN DUGGAN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Bookbinders Strip-Applying Machine, of which the following is a full, clear, and exact description.

My invention relates to mechanism used for joining leaves of cardboard, such, for instance, as are employed for sample books and the like.

Among the several objects sought to be accomplished by my invention, are the following: 1, to enable the joining of the leaves to be accomplished by aid of a single roll of ribbon or muslin to which glue or liquid paste is constantly applied; 2, to enable the leaves to be joined while stationary and fiat, 3, to enable the glue or other adhesivematerial to be heated before being applied to the joining strip or to the leaves or sheets; 4, to generally produce a machine of comparatively great efficiency and simplicity and which is not liable to get out of order.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical section through a joining machine made in accordance with my invention, and showing the joining strip as fed from a roller, treated with a molten adhesive material, and applied continuously to successive pairs of leaves or strips. This view also shows the means for regulating the stroke of the working arm so as to adapt it to different widths of leaves or sheets Fig. 2 is a vertical section upon the line 2-2 of Fig. 1. Fig. 3 is an enlarged plan view of the covered gluing pan and the rollers mounted therein; Fig. 4 is an enlarged plan view of the joining table, a part of the working arm being shown in horizontal section as if cut upon the line 4 4 of Fig. 7 Fig. 5 is a fragmentary vertical section showing a pair of leaves secured together by joining strips, or in other words, showing one form of the finished article; Fig. 6 is a fragmentary horizontal section, somewhat enlarged, showing the means for varying the position of the crank pin 21 for the purpose of regulating the stroke of the working head to suit different widths of leaves or sheets, and Fig. 7 is a fragmentary side elevation, somewhat similar to the left hand portion of Fig. 1, but showing the working head 36 and the slide 42 as moving toward the left, according to Fig. 1.

A frame 8 is provided with bars 9 extending directly across the same, and with brackets 10 having upper rollers 11 and lower rollers 12, these rollers serving as anti-friction bearings. A revoluble shaft 13 is provided with fixed and loose pulleys 14, 14a, and with a sprocket pinion 15. The latter is connected by a sprocket chain 16 with a sprocket wheel 17 mounted rigidly upon a revoluble shaft 18. Also mounted rigidly upon the shaftlast mentioned is a disk 19 provided with a radial slot 20v. Passing loosely through this slot is a crank pin 21 provided with an annular bead 22. A washer 23 encircles the pin 21 and a nut 24 engages one end of the latter as indicated in Fig. 6. A pitman 25 is journaled upon the outer portion 26 of the crank pin, and encircling this outer portion is a washer 27 held thereupon by a nut 28. By loosening the nut 24 the crank pin 2l may be moved radially toward or from the center of the disk, thus shortening the stroke conferred upon the pitman 25 when a disk is rotated'. One end of the pitman 25 is connected by a pivot 29 with a lever 30, the latter being mounted upon a shaft 31 secured in hangers 32. The upper end of the lever 30 is connected with a link 33 by means of a pivot 34, this link being j ournaled to lugs 35 depending from the lower surface of a movable bar 36. The brackets 10 upon opposite sides of the movable bar 36 are provided with guide faces 3,7 which prevent lateral motion of the bar. A slideway 38 is integral with the movable bar 36. Mounted upon the slideway 38 are lugs 39, and j ournaled intermediate of these lugs is a pawl 40 pressed upon by a spring 41 as indicated in Fig. 1. A sliding head 42 is provided with a rack 43 integral therewith, this rack being engaged by the pawl 40 so that in case the sliding head 42 is raised it is supported in its highest position by menas of tthe pawl 40. If, therefore, the slidinghead 42 is raised gradually step by step the pawl 40 locks it at each upward movement and prevents its retrogression. Revolubly supported at-the upper end of the sliding head 42 is a pulley 44. The lower end of this sliding head is provided with a slot 45 within which is a roller 46. A presser foot 47 extends lat- .carrying the sliding head 42 moves alterf nately to the right andto the left, according erally outward from the sliding head and is provided with a composite roller 48 built up of disks spaced apart as shown in Fig. 4. The bottoms of the rollers 46 and 48 are substantially in the same horizontal plane.

Mounted upon su porting legs 49 is a covered glue pan 50, an disposed partially within the samegis a steampipe 51. The pan contains a quantity of glue 52 or other adhesive. If the adhesive employed does not require heat the steam -pipe 51 simply remains idle, no steam being turned on. Revolubly mounted within the glue pan 5() are rollers 53, and disposed adjacent to each of these rollers is a scraper 54 for removing an excess of glue from t e periphery of the same. A shaft 55 supports a continuous strip 56, which is wound thereupon in the form of a roll, as will be understood from Fig. 1. The strip 56 passes below rollers 57 and over the rollers 53. Mounted upon the outer ends of the supporting arms 58, 59 are pulleys 60, 61, for supporting and guiding the strip 56 as the same is fed continuously.

Upon the framework 8 and projecting laterally outwardlyV therefrom are braces 62 supporting a board 63i This board is provided with ways 64 fitted with gages 65. j The leaves or sheets to be operated upon are shown at 66, and the finished strips cut into desired lengths and joined are shown at 67. Guide plates 68 are secured by means of screws 69 to the guide-way 3 8, and the sliding head 42 is free to move vertically in relation to the same.

The operation of my device is as follows A suitable quantity of glue or other adhesive 52 isplaced within the covered pan 50 and steam heat is applied thereto, if desired, by means of the steampipe 51. The joining strip 56 is coiled upon the shaft 55 in the manner above described and is led around the rollers 57 and 53 and the pulleys 60, 61 and 44 and passed downwardly between the rollers 46 and 48. The crank in 21 (see Fig. 6) is now adjusted toward or filoni-the center of the disk 19 and tightened relatively to this disk so that the rotation of the disk gives, within certain limits, any desired degree of thrust to the pitman 25, thereby giving any desired stroke to the movable bar 36. The gages 65 are next adjusted according to the size of the leaves or sheets 66. These leaves. are fed by hand. The operator places them upon the board 63, being aided by the gages 65, which as above explained have already been placed in any desired position. Power now eing applied to the fixed pulley 14 is transmitted to the revoluble shaft 13, the disk 19 begins to rotate and the lever 3() confers upon the bar 36 a reciprocating movement. The result is that the yslideway 38 to the view shown in Fig. 1. As shown in not much glue can remain upon it.

this figure, two pairs of leaves or sheets 66 have just been joined and the strip 68 is lying with its upward face coated with glue. While the device is in this position the operator deposits at once another pair of leaves and immediately the slideway 38 and the sliding head 42 travel to the left, pressure being applied by the roller 46 upon the upper or dry surface of the gluing strip 56, so as to force this gluing strip into adhesive engagement with the cardboard leaves or sheets. The return of the sliding head to the right brings the roller 47 into contact with the surface of the strip, but as the roller 47 is made up of disks it does not materially mar the glued surface. As each successive thickness is added to the stock lying upon the table 63, the rollers 46, 48, gradually climb, thus pressing upward the sliding head 42. As above explained, this sliding head 42 is unable to recede, owing to the gripping action of the pawl 40. When the sliding head 42 reaches its top limit the board 23 is piled up several inches thick with the practically completed stock. A considerable amount of time is saved by the upward movement of the sliding head 42, for the reason that this member, when once raised by a given thickness of stock, maintains practically its level ready for the next thickness of stock, and then travels upward a distance equal to merely that thickness. As it is obvious that the stock may be of different widths when used for different purposes, the adjustment of the crank pin 21 relative to the center of the crank disk 19 enables the movable bar 36 to execute such a stroke as is commensurate with the width of the stock, undue waste of material being thus avoided. Owing to the fact that it has no great amount of connected surface, lor in other words, is practically open,

This arrangement is necessary because the roller at times comes into direct engagement with the adhesive coating carried by the gluing strip.

As will be seen from the above description, l discard all reels or rollers, or ribbon or muslin, except the single roller shown in Fig. 1, and yet I join portions of the stri upon opposite sides of the same pair o' leaves or sheets as will be seen from Fig. 5. Ordinarily two rollers are required for this purpose, one feeding from below and the other from above. I

The advantage of my single ribbon machine is that it leaves the joined sheets iled one on top of the other with heads of s eets all one way. Therefore they can be taken from the oining table, and their edges cut in a cutting machine without further work. This is not possible on the double roller machine as the sheets leave the machine with the head of each pair joined to the foot of the preceding pair by the ribbon, which junction must be cut apart by hand, and the joined sheets laid in proper shape for the cutting machine, all of this unnecessary Work I avoid. It will also be observed that the joining is done not only while the leaves or sheets are lying flat, but also While they are motionless. I find that in this manner the glue on the strip is made to adhere with great firmness to the edges of the leaves or sheets.

While the particular apparatus above described is used for the eX ress purpose indicated, I do not limit myse f to this particular use. Neither do I limit myself to the eXact construction, as reasonable variations may be made therefrom without departing from the spirit of my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of a movable bar, supports therefor, means for reciprocating said ar, a slide-way mounted u on said bar, a sliding head disposed in sai slide-Way disposed to travel in a direction crossing the general length of said bar, a roller mounted upon said sliding head and movable bodily therewith, and means for preventing retrogression of said sliding head relatively to said slide-way.

2. The combination of a movable bar, rollers and guides for supporting the same, means for reciprocating said bar, a sliding head mounted upon said bar and adapted to travel in a direction-crossing the general length of said bar, ratchet mechanism for sustaining said sliding head when moved step by step in said direction, and a board for supporting the stock to be operated upon,

said board being disposed adjacent to the path of said sliding head.

3. The combination of a movable bar, means for reciprocating said bar, a head mounted upon said bar and adapted to travel in a direction crossing the general direction of the length thereof, a roller mounted upon said head, a table disposed parallel to the path of travel of said movable bar and adapted to sustain the work to be pressed, and means for preventing retrogression of said head and roller along said bar.

4. The combination of a bar, means for causing the same to reciprocate, a head connected with said bar and adapted to move bodily in a direction crossing the general length of said bar, a roller connected with said head, means for supporting the stock to be olperated upon in such position that said stoc lies Within reach of said roller when said bar is reciprocated, and means for preventing the retrogression of said head and roller along said bar. A

5. The combination of a table for supporting fiat stock, a pair of rollers disposed one in advance of the other for traveling upon said stock, one of said rollers being smooth, the other having an interrupted surface, and means for moving said rollers relatively to said stock.
